Summary: Not able to serialize nested navigation properties Key: OLINGO-1474 URL: https://issues.apache.org/jira/browse/OLINGO-1474 Project: Olingo Issue Type: Question Components: odata4-server Affects Versions: (Java) V4 4.7.1 Reporter: Alan Macfarlane I have an EDM with the following: <EntityType Name="problem"> <Key> <PropertyRef Name="id" /> </Key> <Property Name="id" Type="Edm.Int32" /> <Property Name="name" Type="Edm.String" /> <NavigationProperty Name="targetItem" Type="Service.item" /> </EntityType> <EntityType Name="item"> <Key> <PropertyRef Name="id" /> </Key> <Property Name="id" Type="Edm.Int32" /> <Property Name="name" Type="Edm.String" /> <NavigationProperty Name="category" Type="Service.category" /> </EntityType> <EntityType Name="category"> <Key> <PropertyRef Name="id" /> </Key> <Property Name="id" Type="Edm.Int32" /> <Property Name="name" Type="Edm.String" /> </EntityType> I can walk the navigation properties successfully using $expand, e.g.: /problems(10)?$expand=targetItem($expand=category($select=id,name)) This returns the expected JSON (summarized): { "id": 10, "targetItem": { "id": 1, "name": "foo", "category": { "id": 2, "name": "bar" } } } But when I try to expand via a select option: /problems(10)?$expand=targetItem($select=id,name, category) I get: { "id": 10, "targetItem": { "id": 1, "name": "foo" } } Any hints how I can get the nested select to include the expanded category in the response? As far as I can see the request is valid (as per OData 4.0 spec) and (unfortunately) the request is being generated by a 3rd party tool so I can't change it. When I include the ExpandOption with the EntitySerializerOptions.Builder should it "just work"? -- This message was sent by Atlassian Jira (v8.3.4#803005)
